The article identifies the advantages of telecentric illumination backlighting in improving the performance of an industrial vision system. Telecentric illumination uses a telecentric lens and a fiber optic light guide or a light-emitting diode (LED) spotlight as a source. It produces enough...

The article offers specifications on how telecentric illumination backlighting functions in improving the performance of industrial visual system. A telecentric backlight directs light emitted from a source into the object with small deviations. It assures that light does not give stray...

The efficiency of formation and time evolution of radiation-induced structural defects and pulsed luminescence in KPb2Cl5 crystals under the action of a single electron pulse ( E = 250 keV, t = 20 ns) have been investigated. The spectra (1.1ï¿½3.8 eV) and relaxation kinetics (time interval 5...

This paper presents results of modeling, experiments, and simulation of transmission of beam and diffuse daylight through straight circular light pipes with and without bends. Analytic method is used in the development of an algorithm for tracing light rays that enter, are reflected from...
